H&K G36 Useless at 200m When Hot


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

A German newspaper has revealed that a Bundeswehr report has said that once the H&K G36 rifle has heated up, the accuracy is significantly reduced to a point where it is useless beyond 200 meters (218 yards). These are pretty serious allegations!



So far, H&K have not responded (or maybe they will just ignore the allegations and hope it means greater sales of the HK416). The XM8, a rifle derived from the G36, nearly became the US Army service rifle.

Damage Industries sling Multi-Mount


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。



Damage Industries recently released their sling Multi Mount. How often are guys changing slings that they need 3, 4 or 5 different sling attachment points on their rifles? I see the utility of these types of devices for departments or units that maintain a fleet of rifles whose users can choose their own slings. But for the average shooter, it seems like you’re going to be fine with either a QD, HK hook or slot.

Using a multi mount attachment does start to make sense, though, when you look at the economics. An inexpensive rail sling attachment that has a couple attachment options and doesn’t weigh significantly more or take up any more space on a rail than a multi mount presents more value than a device that only offers one attachment method. If you end up changing your sling after a few years, not worrying about buying a new mount is worthsomething.

The Damage Industries Multi Mount reminds me of the VTAC LUSA and the Blue Force Gear Rail Mount Sling Loop. Damage Industries has married the best aspects of these devices while holding the price to $25. The Multi Mount adapts a sling to a 1913 Picatinny rail via a pair of rotation limited QD sockets, HK style or MASH hooks, or slotted directly through the device. It’s made in the U.S. of billet aluminum with Mil-A-8625 type III class 2 hardcoat anodizing. The only thing that worries me is running a steel HK or MASH hook through an aluminum fixture. I’ve seen steel hardware really chew away at aluminum sling attachments over the course of a deployment.

Damage Industries is currently shipping black and dark brown versions and is gauging interest in a FDE version.

FG-42 Tactical


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

I can barely contain my excitement! A german firm called Tactics Group will be producing a "tacti-cool" version of the German WWII Fallschirmjägergewehr 42 (Paratrooper Rifle 42) aka. FG-42. It will feature all the accessories found on modern rifles.



The new FG-42 will feature polymer furniture, a spring-powered recoil reducing buttstock, AR-15-compatible pistol grip, picatinny rails a fancy muzzle brake. It will be chambered in 7.92x57mm Mauser, the same cartridge as the FG-42. The felt recoil is said to be reduced to about the same as a .223 Remington. The company is working on constructing a magazine with a higher capacity than the standard 20-round FG-42 magazine.



There will be two variants, a carbine model (pictured above) and a rifle length model.

Remington Contract


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

Remington has acquired a contract to supply the US Army of 24,000 units of M4 Carbines.



The M4 and M4A1 carbines are the US Army’s primary individual combat weapons and will be produced by Remington to the US Army’s M4 technical data package. The Army has initially ordered 24,000 M4A1 carbines from Remington; deliveries will start in September, 2013.

“The innovation, quality and reliability of Remington rifles have made our company a leader in defense markets around the world,” said General Michael W. Hagee (USMC, Ret.), a Remington Arms board member and former Commandant of the Marine Corps.

“The chance to expand our strong military and defense presence producing M4s for the U.S. Army is a great opportunity,” added General George Joulwan (US Army, Ret.), also a Remington board member and former Supreme Allied Commander of Europe and head of NATO Forces. “We are proud and honored to serve those who serve all of us.”

Remington, in operation since 1816, is one of the oldest continuously operating manufacturers in the country. The M4 and M4A1 carbines will be produced at Remington’s core rifle manufacturing facility in Ilion, New York.



George Kollitides, Chairman and Chief Executive Officer of Freedom Group and Remington Arms, noted, “Over the past four years, we have made a substantial investment in Remington’s ability to compete in the government small arms space by modernizing our production facilities, focusing our research and development on end-user requirements, and ensuring consistent and repeatable quality in a high volume, high mix manufacturing environment. We see this award as proof that an American manufacturing company can still expand its product offerings and compete in this modern age to provide best in class weaponry to our troops defending freedom around the globe.”

Army Buying M4s

Army buying M4 Carbines from Remington, Colt Still Earning Royalties For M16 Design.



Mr. Curtis over at Gear Scout broke the news that Remington will be manufacturing M4 Carbines for the US Army.

According to the Department of the Army’s Chief of Legislative Liaison, the Army today executed a delivery order on an existing contract to buy 24,000 M4/M4A1s worth $16,163,252.07. The order comes as line 001 on an IDIQ contract for up to 120,000 carbines worth $83,924,089.00, though U.S. Army Contracting Command lists the “Max Potential Contract Value $180,000,000.00.” The rifles will be made at Remington’s factory in Ilion, N.Y., from the Colt technical data package and, by my math, will cost about $673 a copy. That’s a hell of a group buy price.

This comes as no surprise. In 2009 the US Army took control of the M4 TDP (Technical Data Package), allowing the Army to second source production. The DoD likes to spread production around in order to maintain a "manufacturing and industrial base".
Colt will still receive royalties from the DoD for any guns derived from the M16 until 2050! I doubt anybody at the time thought the M16 would still be in service today, nearly 50 years later (the previous service rifle, the M14, only lasted 11 years).

"How to Look Like You're In the Special Forces"

私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。


Photo Source: US NAVY SEALs SDV Team-1 Operation Redwing from Defense Industry Daily


1. First, go buy the biggest watch you can find. A foreign special services officer asked me once whether we recruited guys based on the size of their watches or whether we bought everyone a big watch as a reward after training.

2. Cut the sleeves off your shirt. It’s hot in the Middle East, and guys would cut the sleeves off their operational uniforms. It makes sense in certain situations, but I had to tell my team, “Look, I know it’s hot, but I need you to meet safety parameters. You’re gonna get scratched.”

3. Make it your boss’s job to tell you to get a haircut and a shave.

4. Wear sunglasses. Everywhere. I’ll tell my team, “Hey, we’re inside. We can take off our sunglasses.” But they don’t.

5. Keep quiet. The baddest guys I know are also the quietest. The guy who’s talking about doing badass stuff? He’s probably not the biggest badass in the room. It’s a little like that guy on the football team who wears his letterman jacket all the time.

6. Never say “no.” Your first reaction has to be, “Yes, I can do that,” and then you figure out how. If the president asked me to go to the moon tomorrow, I’d say yes. Then I’d say, “I’ll need some training. And someone who can fly a rocket.” — As told to Brendan Greeley

Econo-Can: A $55 Suppressor


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

American Specialty Ammo is selling a registered NFA suppressor for $55 (+ $200 tax stamp) that is nothing more than an adapter to attach a car oil filter to a 1/2-28 threaded barrel. The first bullet punches a hole in the end of the oil filter.





You can buy "spin-on" oil filters for $10 - $20. A used oil filter (soaked with old oil) will only improve its efficiency. Internally oil filters contain fibrous material designed to filter out contaminates from the oil. I think they would eventually wear/burn out when used with firearms.


An oil filter cartridge


This is a very clever concept. It makes me wonder why someone doesn't make a universal suppressor adapter and a range of tubes for various calibers.

Meprolight M21 dual-illuminated Reflex Sight

私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。



With combat experiences from five major wars and concurrent anti-terrorism operations since its founding in 1948, the Israeli Defense Forces or IDF is one of the first military to understood the advantage of reflex sight on small arms for every infantryman. The main reflex sight used by the IDF for the last 20 plus years is the Meprolight M21. It features the always-on dual-illumination by fiber optic collectors during the day and it uses tritium illumination for low light and nighttime.



The Mako Group is the authorized distributor of Meprolight rifle sights in North America. I had a chance to try out a Meprolight M21 reflex sight during an Israeli style carbine course offered by Mako Defense, a sister company of the Mako Group. The version that I tried has the “X” reticle. The M21 is also available with the 16 MOA triangle reticle, 4.3 MOA dot, 5.5 MOA dot and the bullseye (a dot inside of a circle). The tritium lamp has a 10-year guarantee by Mako. It typically lasts up to 14 years before the tritium became unusable. The tritium illumination unit is replaceable by factory service for a reasonable cost. The current production model is actually the Mepro M21m. The –m suffix is for modular design and because of that, every component on the M21m is replaceable and upgradeable. When mounted on an AR15 flat-top, the M21 has lower 1/3 co-witness with iron sights.






The M21’s reticle has an amber color and its 30mm objective lens’ coating has a green color tint to it. Under the bright daylight, the green lens coating is hardly noticeable. As the light becomes dimmer, the green color appears greener. Since human eyes are more sensitive to the green color, by using a green lens tint it helps to increase the optical contrast and makes the reticle stands out. On a reflex sight design, using the green color coating is a common technique to compensate for a dim reticle. In the M21’s case is its tritium lamp. The majority of the M21’s fiber optic collectors are located in the front of the sight with some in small windows in a horseshoe like pattern around the sides and the top. All the fiber optics is behind protective translucent panels with a discreet light grey color.

I found the M21’s amber color reticle works fine in daylight in both the desert and foliage environments and it is adequate in the darkness. The reticle is also sharply focused and without blooming. However, like other fiber optic and tritium lit sight, it has some issues in certain light conditions. The illumination is barely visible in the low interior lighting of a house. Where neither the fiber optic collects enough light nor the tritium lamp is bright enough. According to the Israeli technique, if you can see the target through the objective lens tube, you will hit it at close range. Another oddity is that in a very bright sunny day, if the shooter is in the shadow of a building and looking through the M21, sometime a bright background would washout the reticle. Although the M21 is less prone to that than the Trijicon reflex sights because it has some of its fiber optics on the sides. Not that the M21 is bad, in fact it works beautifully in most light conditions. Just remember that the fiber optic light collector technology has its limitation.




The M21’s tritium illumination is night vision compatible and it has less blooming than other tritium sights through the NVG. The company gets the tritium from the same Swiss manufacturer that also supplies Trijicon. According to Mako, the main difference is that Meprolight only buys the raw tritium instead of having the Swiss to build the whole illumination unit like Trijicon. Meprolight applies their proprietary treatments to the raw tritium before packaging it and also use higher quality focus lens in their tritium tubes.

The Meprolight M21 was specifically developed according IDF’s requirement. The sight has to be tough enough to withstand the punishment by 18 years old conscripts. The IDF is expecting the M21 to last for at least 20 years of hard use. The sight uses no battery, has no external switch, it’s always on and ready to use. The M21’s aircraft grade aluminum housing is sealed against the environment and it’s waterproof. Both the windage and elevation adjustment dials are flush mounted. The M21 features an adjustable QD mount with dual QD levers for mil-spec 1913 rail. Interestingly, the IDF had actually tested the various QD levers on the market. They have found that while the cam types like LaRue and ARMS are better for retaining zero, the cross bolt type that is on the M21 has more tolerance for mishandling. Mako also offers the M21 with a co-witness M16 carrying handle mount. Noted that the user can’t switch out the mount, it’s factory calibrated to the sight’s lens and it’s permanently installed.

Glass For Gunfighting


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

object: rounds on target SOLUTION: A GOOD TACTICAL OPTIC!



Iron sights have become the powder horns and ramrods of the modern Army. Today’s warfighter is issued an M4 and trained to use a close-combat optical sight for the simplest and most obvious of reasons: Optics produce more accurate hits. When the Army first got serious in the 1990s about testing what are generically, although inaccurately, referred to as “red dot sights,” it found that soldiers fired significantly higher qualification scores. The result was the awarding of a multi-year, multi-million dollar contract in 1997 to an innovative Swedish company whose name is virtually synonymous with the whole category of close-combat optics: Aimpoint.



It’s important to understand the Army’s core motivation of improving accuracy as the underlying reason for issuing a close-combat optic (CCO) in the first place. Combat marksmanship is no different than Olympic target shooting in its two fundamentals of trigger control and sight picture. You just do it a lot quicker! Certainly trigger control is by far the more important of the two components of accurate shooting, however, you can’t buy skill. From an overall operational standpoint of improving a soldier’s marksmanship, the Army realized it couldn’t buy good trigger control, but it could buy better sights.

Study Reveals That Guns Make Men Look Taller And Stronger


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

With gun in hand, a man of any size appears bigger, an altered notion that probably occurs at a subconscious level, a new study suggests.



The research, funded by the U.S. Air Force, reveals a seemingly simple mechanism that was even in the brains of Neanderthals, and possibly common even to chimpanzees, to measure whether they would win or lose a fight with an aggressor.

"There's nothing about the knowledge that gunpowder makes lead bullets fly through the air at damage-causing speeds that should make you think that a gun-bearer is bigger or stronger, yet you do," lead study author Daniel Fessler, an associate professor of anthropology at UCLA, said in a statement. "Danger really does loom large — in our minds."

Holding hands

Fessler, who is director of UCLA's center for behavior, evolution, and culture, and his colleagues ran several tests in which participants were asked to estimate the height of men based on photos of their hand, which was holding one of various objects, including a handgun. In some of the tests, participants also rated the object holder's overall size and muscularity based on a scale of six photos showing men with progressively more muscular bodies.

In one test, participants looked at four photos of different hands, each holding one of four objects: a caulking gun, electric drill, large saw, or handgun. [Infographic: US Gun Ownership]

Participants judged the gun-holders, on average, to be 17 percent taller and stronger than those rated as the smallest and weakest men, which in this test ended up being those holding caulking guns. Hand models holding the saw and drill were judged as the second and third, respectively, in terms of size and strength.

(The test involved 628 participants, 497 of them female, and averaging 34 years old. To get a sense of participants' sizing accuracy, the researchers also had them do the same height estimation for images of progressively taller men as well as a set of images showing progressively more-muscular men.)

Perhaps the phenomenon had to do with the fact that in pop culture guns are usually associated with bulky men (think Rambo or Arnold Schwarzenegger). To find out, the researchers ran the same test but this time showed hands holding a kitchen knife (a stereotypically female object), a paintbrush (a stereotypically male but benign object) or a toy squirt gun.



On average, the 541 participants in this test judged the men holding the most lethal object, the knife, as the biggest and strongest of the bunch, followed by those holding the paintbrush and the squirt gun.

"It's not Dirty Harry's or Rambo's handgun — it's just a kitchen knife, but it's still deadly," study researcher Colin Holbrook, UCLA postdoctoral scholar in anthropology, said in a statement.

Neanderthal mental mechanism

The researchers concluded that the results of the study can be explained neither by such factors as real-world associations between body size and guns — gun owners aren't taller than non-gun owners — nor by cultural associations. Rather, they suggest a mental mechanism in a distant ancestor was modified through the years and still exists today.

"In a species with a complex behavioral repertoire like our own, when two parties come into potential conflict there are many different features that can contribute to the likelihood that one side or another will win," including size of the individual, level of coordination within a coalition, and possession of weapons, among others, Fessler told LiveScience,

Fessler and his colleagues are proposing that one way the human mind might make sense of all of these variables, in a way that would allow a quick decision (to fight, retreat or negotiate), is to have a visual representation of an individual or group's formidability. In the mind, this formidability would be represented by size. [10 Mysteries of the Mind]

"Every time you have a new piece of information that tells you how dangerous that other party is relative to yourself, you update the picture by either enlarging it to make them seem [more muscular] or shrinking it and making them seem smaller and less muscular in the mind's eye," Fessler said.

The study, detailed online today (April 12) in the open-access journal PLoS ONE, is part of larger project funded by the Air Force Office of Scientific Research to understand how people make decisions in situations of potential aggression.

While this work someday could have practical implications for military strategies, in the near future the research is more about understanding complicated humans. "This is a first step in what we hope will be a number of investigations where the ultimate goal is to understand cognitive processes that underlie decision-making in situations of potential aggression," Fessler said during a phone interview.

Kimber Solo Carry


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

Micro-compact striker-fired 9mm — the ultimate undercover pocket pistol!



Weighing just 17 ounces and chambered for the 9mm cartridge, Kimber’s Solo is destined to become a favorite of those that trust their lives to their carry guns. Shown are the Solo Carry Stainless and Solo Carry.


There was no elaborate fanfare or warning that something really sensational was about to happen in the gun industry earlier this year. Kimber—a company best known for their extensive line of 1911s—introduced a micro-compact, striker-fired 9mm autoloader that seems perfect for off-duty, undercover or back-up use. Before it was even released, I only heard rumors and had to investigate.

What I read intrigued me. Clearly Kimber had not merely followed the template that other manufacturers use, but rather started with a fresh page and designed a gun that, from top to bottom, is built for deep concealment. Recently, I was given a chance to actually handle one of the brand new Kimber Solo pistols. To say that I was impressed is an understatement. Small, sleek and lightweight, Kimber’s 9mm micro-compact also features great sights, a smooth trigger and ambidextrous manual safeties and magazine releases. In my eyes, it’s everything that a law enforcement back-up handgun should be.



The Kimber Solo’s stainless steel barrel measures 2.7” long and mates directly to the slide of the pistol.


Many will look at the Solo Carry and mistakenly assume that it possesses a double-action-only trigger. I know that I did. But the striker is loaded to nearly 90 percent, and the balance of movement cannot be felt as the trigger is pulled. Therefore, the best description for this action would be “single-action/striker-fired.” The Kimber system also utilizes a firing pin safety that prevents the gun from being fired unless the trigger is fully depressed.



Kimber lightly bevels the mag well of the Solo Carry for fast and sure mag reloads. Note the ambi mag release.

LWRCI REPR 7.62×51mm


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

SBR variant Rapid Engagement Precision Rifle that delivers at extended ranges!



The 12-inch-barreled REPR is much more than a SBR chambered in 7.62mm. LWRCI’s REPR can be considered for the full gamut of operations — serving as an entry weapon, patrol rifle, or precision tactical option in the LE realm. Shown here with a 4×32 BROWE Combat Optic mounted.


A truly versatile rifle is one that continues to transform itself, satisfying multiple roles with equal aplomb. The LWRCI REPR chambered in 7.62×51mm is such a rifle. Its versatility combined with relentless gas-piston reliability is making the LWRCI REPR a favorite among our troops and law enforcement personnel.

The LWRCI Rapid Engagement Precision Rifle (REPR) is offered with 12- and 16-inch barreled models, as well as an 18-inch Designated Marksman model and 20-inch Sniper model. For civilians or even law enforcement, the 12-inch barrel is not “standard” and requires a BATFE tax stamp. The REPR features a “flattop” receiver and comes with either a Flat Dark Earth or Olive Drab Green Cerakote finish, which offers unparalleled abrasion and corrosion resistance. This self-lubricating characteristic of Cerakote means that the rifle can be run with less lubrication—especially useful when operating in the desert or other dusty environments.



Many features set the LWRCI REPR apart from competitors, including its short-stroke gas piston operating system and proprietary nickel coating that nearly eliminates corrosion.


The REPR rifle utilizes LWRCI’s patented self-regulating, short-stroke gas-piston operating system, ensuring reliability in the harshest theaters of operation. LWRCI literature points to several industry leading technological innovations incorporated in the REPR. LWRCI has sought to engineer a complete solution to the deficits found in the direct impingement AR family of rifles and carbines, and was an early innovator in the AR gas-piston surge. The principal improvement comes from eliminating the venting of hot, carbon-laden gases into the receiver and bolt carrier group. This reduces the cleaning requirements associated with direct gas-impingement AR. It also means the bolt carrier group and associated springs are not subjected to the searing heat of the tapped gasses; this being one of the major causes of small parts failure. The REPR’s four-position gas setting further ensures a user can adjust to changing environmental conditions — not to mention better employ a suppressor if a mission dictates this.



The LWRCI REPR comes standard with flip-up back-up iron sights (BUIS) that co-witness with most optics. Range evaluations show nothing sacrificed when “going to irons” with the REPR at moderate distances.

Glock baseplates from Vickers Tactical


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。



Perhaps you thought there wasn’t anything left for the aftermarket to address on the Glock platform. Larry Vickers is proving you wrong by putting out a new magazine base plate. The new mag plate is wider, offering the ability for the shooter to more easily strip a stuck mag from the magwell. It’s also got a matrix of dots that can be used to number/identify a mag. No word on price or availability, yet.

Does your mancave needs more Beard?


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。



So, why draw Costa? Why not. JK’s earlier work “Spirit of a Warrior” features a badass with a Spartan-looking shadow. Turning to Costa, the man has a gladiator fetish and a following. Heck, even his Beard has a following. And, it turns out, Costa’s been looking for a way to satisfy his fans’ hunger for autographs and pictures; so here we are. JK does his thing, Costa takes care of his fans. Win-win.

JK will offer a series of seven drawings, the first of which is available today from JK’s website,www.tacticaldrawings.com, for $45. The remaining six drawings will follow at roughly 3-4 month intervals.

Costa is giving 100 percent of his proceeds to the Stars and Stripes Foundation. JK’s invested his time and talent heavily in this project. He can’t afford to donate 100 percent, so JK’s donating a portion of his proceeds to Stars and Stripes Foundation as well as his church.

I know what you’re thinking: “$45 for a drawing? Of Costa?” These are not shop wall pin-up posters. This is an 18” x 12” water-colored, pencil drawing printed on 100 pound matte paper using a digital press bearing Costa’s digital signature.

Consider all the work that went into the drawing. JK spent 20 hours researching and preparing. He made period-specific props from cardboard and found a gladiator-esque model to guide his representation of the “spirit” warrior. He roped-in Pima County Deputy Sheriff Avery Cox as the model. (As an aside, JK told me, “I feel sorry for any criminal caught by that guy.”) He added some of his own touches to the armor, but the shoulder, arm and shinguards are period-accurate, as is the shield. Russell Crowe fans may recognize the helmet is inspired by the one worn by Roman General Maximus Decimus Meridius in the film, “Gladiator.”

Next-Gen M240LW Battle Beast


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

Barrett’s re-engineered, trimmed down classic 750-RPM equalizer



Serious reach! A solid M240 crew can lay down accurate fire out to 800 yards when shooting from the weapon’s bipod, and 1,800 yards from a tripod.


The U.S. military has called upon the M240B belt-fed medium machine gun for two decades to provide troop support with suppressive and direct fire. These weapons have put millions of rounds downrange, and littered the sand with hot empty brass, links and blood when called upon. The M204B is reliable, but troops in the field alerted their higher ups that improvements were needed. A request went out to “cut the fat” from a weapon that incorporates design features that date back to the end of WWI. Barrett Firearms, dependable provider of the M107 .50 semi-auto, took the initiative and designed the M240LW to take advantage of cutting-edge manufacturing techniques.




Battle Experience

Three soldiers comprise a normal M240B team, but many soldiers are trained on the weapon so they can man the gun if needed. One soldier with M240B experience is 24-year-old Aaron Fouraker.

Fouraker, a self-claimed shooting enthusiast from Russellville, Arkansas, was fascinated with firearms and shooting from an early age. After a year of college, Fouraker joined the military. “I joined the Army in May 2005,” Fouraker said, “and got assigned to Ft. Bragg and the 82nd Airborne Division in June 2006.” When he got to Bragg, Fouraker was assigned to Delta Company 154.


The Barrett M240LW utilizes the same soldier-familiar gas adjustment assembly found on the M240B.

Aussie Top Shots

Defence Force Diggers take their small arms training to the peak of potency!



Image: (U.S. Air Force photo by Tech. Sgt. Jeremy Lock) (Released)


I was first acquainted with the Australian military’s small arms program through the U.S. Army Reserve Shooting Team. Having competed with their shooters at NATO-sponsored events, I found them to be quite skilled. That’s no surprise—all the major member states of the Commonwealth have first-class militaries. In fact, the procedures and courses of fire that comprise NATO combat competition were first invented in the Commonwealth and these soldier-shooters are the ones to beat. During a visit to Victoria, I had a chance to visit three Australian military facilities.



Australian-issued F89 machine guns (FN Minimi or M249) wear the same optic as the F88. ADF troops use this as an automatic rifle like U.S. forces, but some consider the Aussies’ training approach to be a bit more rigorous.


The Australian Defence Force (ADF) consists of the Australian Army, Royal Australian Navy and Royal Australian Air Force (RAAF). The ADF has a strength of almost 60,000 full-time active-duty personnel, 22,000 active reserves and 22,000 standby reserves. While small by U.S. and Asian standards, the ADF is technologically sophisticated and, man-for-man, rivals the best militaries around the world in terms of equipment and training. The ADF is supported by a significant budget and the ability to deploy worldwide.



The ADF recognizes up to a dozen official qualification courses for each weapon. These LF (Live Fire) courses for rifle, automatic rifle and pistol are chosen based on the individual soldier’s unit of assignment.


Australia’s military program began in January 1901 upon becoming an independent nation. In 1911, the Royal Australian Navy was formed, and the Royal Australian Air Force was established in 1921. Initially, the services reported to separate ministers. A common chain of command was realized after Vietnam with the creation of Chief of the Defence Force Staff and official formation the Australian Defence Force in 1976.



As with other Commonwealth militaries, the ADF still maintains good gunnery skills for MGs. Gun teams learn gunnery from the bipod and tripod for sustained fire.

Black Rifle Company SASS 6.8 SPC

私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

Semi Automatic Sniper System boasting tactical advantages through innovation!

When the SASS (Semi Automatic Sniper System) was originally developed as a 7.62×51mm NATO rifle for the U.S. Military. Its intended purpose was to provide a reliable semi-automatic precision rifle in a familiar platform that could be issued on a wider basis. While the bolt rifle has its place, our current area of operation is not always conducive to the lower rate of fire and magazine capacity. It also requires specialty training, as it is a completely different platform. By using what is easily the most familiar rifle platform our troops have, the train-up is far less. There was also the added benefit of magazines and other interchangeable items in inventory from the Mk 11 Mod 0 project.



Black Rifle Company’s SASS is accurate, reliable, and true to the Semi Automatic Sniper System concept, shown here with a Leupold Mark AR scope and GG&G XDS bipod.


Although a typical SASS-style rifle is probably not as pinpoint-accurate as a bolt gun, it is pretty close. Semi-automatic precision rifles have come a long way, and there are several solid versions inspired by this rifle in various chamberings. Priced comparably with many other AR-type rifles that yield precision accuracy, they have become truly versatile systems. It really has opened the platform up to the police world, a world where the semi-auto sniper rifle is still quite rare.



Scoped AR type rifles like the SASS really need an extended charging handle to work properly, allowing it to be operated around the optics.


The high-quality quad rail is perfectly suited to this rifles mission. There was plenty of rail space for accessories yet a nice soft area for precision hand holds from positions other than prone.


A simple birdcage flash suppressor was provided, but other flash suppressors or muzzle brakes are available by request and can be added as necessary.


Leupold’s Mark AR scope is very simple, lightweight and well suited to just about any tactical environment. The glass is clear and the mil-dot reticle remains a favorite of many operators.

Back to Batangas

私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

Searching for the few remaining Filipino balisong craftsman!

Before the arrival of spring-assisted or fully automatic pocket knives, before manufacturers started putting holes in their blades and thumb studs, there was the original one-handed opening knife. The Balisong is a folding pocket knife with two handles counter-rotating around the tang. When closed, the blade is concealed within grooves in the handles. This is loosely known as a butterfly knife.

The Filipino Balisong knife was spread around the world by American soldiers returning from World War II. Translated from Tagalog, the word “Balisong” means “broken horn,” as the original Balisongs were made from.

A town in Batangas, known as Barrio Balisong, is where legend Perfecto de Leon is credited with developing and manufacturing the first Filipino version of the Balisong knife in 1905. Since then, the Balisong has become perhaps the most infamous Filipino weapon to date. Locals in the Philippines are much more likely to carry knives than guns. Knives are commonly carried as tools by farmers and used by street vendors to prepare coconuts, pineapples, other fruits and meats. This has led to the Philippines being known as a ‘blade culture,” so much to the point that the neighboring country of Palau has a term for Filipinos: chad ra oles, which literally means “people of the knife.”





Three Batangas Balisongs from Ona’s shop. All handcrafted from 5160 spring steel and using various materials for the handle scales ranging from Kamagong wood to horse and deer bone.



This is the model AP2 made by Armand Palacio. Like the AP1, it is also made from D2 steel and features titanium handles with a very unique pattern cut into the handles, yet another stamp of Armand’s distinct style.



At the shop, Ona displays his lightning fast speed as the author’s camera struggled to capture it. He is known for his two-handed deployment of the Balisongs simultaneously. In the background hanging, many other tools can be seen that are both for sale and collectables including US bayonets and machetes.

ATI Talon Shotgun Gear


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

Enhancements that will turn your scattergun in a CQB tactical powerhouse!



ATI’s Talon stock and forend system was easy to install, was very solid, and the Scorpion buttpad made shooting comfortable. The six-position stock allows the shooter to quickly and easily adjust the gun to allow for the most comfort and accuracy.


The carbine is slowly supplanting the shotgun in many departments these days. It is prevalent enough that in some cases new officers have never even seen a tactical shotgun, let alone used one. With it slowly fading from the police world, it is easy to forget how versatile and powerful this venerable workhorse is—especially the pump shotgun.

Although semi-automatic shotguns are taking over the competition world, and in many instances the tactical environment, the pump shotgun is still the favorite of many. The biggest reason, of course, is its complete reliability with all types of ammunition. No need to change buffers, pistons or anything else. It will run the lightest gas or riot load or the heaviest magnum. It will run wet, dirty, muddy and in any environment. Given the correct ammunition, a pump shotgun will do just about any job a police officer is called upon to do with great effectiveness.

With the exception of long ranges and some limited hard target penetration, it will even do most anything a rifle will do. It just takes some practice and a bit more effort to control recoil. And the recoil has been trimmed down considerably with the latest in low-recoil rounds. It may not be the most popular weapon these days, but the pump shotgun remains one of the most effective, and just as important, it’s affordable.



Using the Triton Mounting System—built from anodized aluminum—one can change between a buttstock and a pistol grip simply and quickly.

Brugger & Thomet’s APR338


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

.338 Lapua Mag anti-personnel rifle for long-range precision!



The folding buttstock is adjustable for length of pull, cheekpiece height and buttpad height. It has an integral monopod and handstop along with two flushcup sling points.


Well, no one will mistake that for a hunting rifle,” I thought, as I took my first look at the Brugger & Thomet’s APR338 .338 Lapua Mag. This gun was conceived and built from the ground up specifically for long-range sniping applications. Matte black, steel and aluminum, without any smooth curves or fancy engraving—it’s all business.

The action is a single rectangular block of steel measuring 9.5×2x1.75 inches. A 9.5-inch Mil-Std-1913 rail is bolted to the receiver with six screws. The rail has 40-MOA of slope built in to extract the maximum possible elevation travel from the standard Schmidt & Bender optic. The rail also sports a flip-up aperture rear emergency backup sight, though I can’t imagine it will ever get much use on this type of rifle. A fully protected bolt stop/release is attached to the left rear with a solid steel pin. The bolt is a three-lug, 60-degree, short throw type. One full inch in diameter with various lightening cuts, the construction seems unique. The bolt head is attached to the bolt body via two large diameter roll pins. The head itself is of conventional design with a plunger ejector and spring-loaded snap over extractor in the top right lug. A long groove a little over 0.25 of an inch wide provides the bolt stop surface as well as the anti-bind rail. This prevents marring of the bolt lug by the bolt stop. An interesting rearward curving bolt handle with a non-metallic ball end is fixed to the rear of the bolt body. The curve places the ball directly above the trigger, making fast bolt work a simple affair. A special tool is provided to take down the firing pin system.



Folding to the left side, the stock latches in both positions via a button seen here above the base of the monopod.


The 27-inch fluted barrel is screwed into the receiver in the conventional manner, but in addition to the flutes there are wrench flats cut into the shank at the receiver junction, which permit a simple vise/wrench combo to remove and replace barrels rather than a special barrel vise. This is unique in my experience, and should make field re-barreling work a little simpler.



The muzzle brake has a threaded section protected by a knurled cap. The suppressor screws on over the brake and seals against a tapered surface, while a folding front sight is built into the brake.


Twist rate is 1-in-11 inches, which will be only just adequate to stabilize 300-grain projectiles. It is of a fairly light Palma-type profile, 0.75 of an inch in diameter at the muzzle and 1.5 inches at the breech. The business end of the barrel is equipped with a large two-vent muzzle brake, which is threaded and has a knurled thread protector permitting attachment of a sound suppressor that goes over the brake vents and seals against a tapered surface. A flip-up front sight is attached, completing the emergency sight system.

The sight base and Mil-Std-1913 rail have small transverse holes that are used to attach the supplied mirage band. Commonplace in competition rifles, I’ve rarely seen one used in the field, though it can prove useful during training sessions, where a number of shots will cause enough barrel heat to distort the sight picture.

Apex Extended Carbine Rail System

私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

As everyone knows there are a huge number of addons for the AR15 family of rifles. Some of these aftermarket parts are very good while others are best ignored. I recently found a new extended carbine rail system from Apex that’s well worth considering as a replacement for your current GI grip or traditional four rails.



At a weight of only 8.1 ounces with three extra rail attachments the weight is considerably less than the usual free float rail system. Most standard configurations have four full length rails which are seldom used in full and just add weight. They can also be pretty rough on your hands unless you add rail covers, which increase the bulk and size of the rails.

The Apex extended carbine system allows the AR15 owner to add assorted short rails to a greater number of locations than a standard system. Extra short rails of one inch to four inches can be placed in eight locations around the entire tube utilizing the milled slots. Most of us only need a flashlight mount and possibly a vertical grip. If you want to add additional items just add an appropriate size short rail in the location best served for that add on. The Apex rail system has the capacity to add four QD sling attachments; two on each side. If you use a single point sling no problem just leave them open for later use if needed.
The top rail is 7.5 inches long and mates perfectly with the receiver rail. The external diameter of the tube is 1.970 inches, which is much less than standard rail systems.


This photo shows the textured “Gator Grip” on the Apex rail

Apex has also solved the rough surface problem most rails have by milling a grip surface they call a Gator Grip. This gives the shooter a firm grip without being abrasive to the shooters hands.

Adcor Bear 5.56×45mm


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

“Brown Enhanced Automatic Rifle” featuring an advanced piston hybrid system!



The Adcor BEAR was designed for the purpose of upgrading the basic infantry weapon. The BEAR—shown here with a SureFire M900V vertical foregrip and Trijicon ACOG—surpasses a conventional operating system by utilizing a unique gas/piston hybrid that builds on the strengths of each system.


At first glance the Adcor Defense Brown Enhanced Automatic Rifle (BEAR) look likes a standard AR-15, but if by second glance its enhanced features have not jumped out at you, then you need your eyes examined. Piston systems are fine and good, but the BEAR is designed to compete in a future military rifle improvement program, the BEAR is not a conventional piston system—it is a hybrid.

The BEAR system takes the best of a variety of the other systems and builds on their strengths. It a modified AR-15 bolt carrier, with the most noticeable difference being a long rod attached in place of gas key. The appearance of the BEAR is reminiscent of the AK-47 bolt group. The end of the bolt rod fits into a short tappet near the muzzle of the rifle that receives the force of the exhaust gases. The tappet is propelled back sharply for a very short distance, and this movement pushes the bolt rod backwards allowing the bolt to unlock and recoil under the kinetic energy of the discharging cartridge. All of the hot exhaust gases stay in the front of the system and out of the receiver, which is the big benefit of a piston system. The BEAR overcomes the adverse mechanical influence of the piston slap and subsequent carrier tilt by using the length of the bolt rod as a mechanical guide, thus keeping the bolt from from wobbling around inside the receiver. At its core, the system is a “short-stroke” piston rather than the short-stroke system more commonly seen in AR piston variants today.



BEAR’s bolt carrier and key design requires two pieces—carrier and piston key—as it would be impractical to manufacture the bolt carrier and long piston rod as single piece.


The bolt carrier and key are is made by Adcor. The BEAR design requires two pieces—carrier and piston key—as it would be impractical to manufacture the bolt carrier and long piston rod as single piece. With more common short-stroke piston systems, the bolt carrier and key are one-piece. This design is touted to be as superior to the Mil-Spec carrier, where the key is screwed onto the carrier from the top and then the screws are Loctite and pinned to prevent them from backing out. In the world of do-it-yourself kit-built ARs, there are concerns that if the bolt carrier is of inferior production the screws can back out, which may cause the weapon to jam very soundly. This is generally not an issue with factory-built rifles like the BEAR, where assembly jigs and precision tools are used.



The dustcover is slightly modified to function with the BEAR wiper system, which is fitted with springs that push the wiper outwards and fill the ejection port, effectively sealing it to significantly reduce the infiltration of debris.


The gas system can be adjusted by turning the regulator valve located in the forward part of the gas block. The gas regulator value is available with either two or four positions of adjustment. The four-position valve is more military oriented. It can be opened or closed down for suppressors or running a very dirty weapon. The in-between positions are for best function depending on ammunition type.



The gas system can be adjusted by turning the regulator valve located in the forward part of the gas block, which is available with either two or four positions of adjustment.


There are many flavors of operating systems for the modern rifle. The original AR-15 design is the direct-impingement system, where gas is vented from the barrel via a tube and directed against the key to force the bolt rearward. Direct impingement is simple and very lightweight.
Its principal disadvantages are that the gases and the associated debris are vented inside the upper and lower receiver, as the heat of the gases reduces the life of some metal components and critical lubricant is dried out.

With the short-stroke piston system, a piston rod is a separate component. When gases are exhausted from the barrel they strike the face of the piston rod. The rod is pushed violently towards the bolt. The striking of the bolt carrier by the piston rod starts the bolt backwards. The advantages of the short stroke systems are that it is lightweight and it is cleaner as gases do not enter the receiver. However, a potential disadvantage is related to the mechanical forces acting on the bolt carrier. The movement of the bolt carrier can “tilt” and may be the cause for premature wear and damage to the bolt and upper receiver.

The AK-47 is a familiar example of the long-stroke system. The gas piston is attached to the bolt carrier and extends far in front of the bolt and the face of the extended piston receives the blast of gas directly. It is a very simple and rugged system; however it is also heavier, both in terms of weight and as the mass relates to momentum and the functional effects on the shooting characteristics of the rifle.

Close inspection of the dustcover reveals that the detent is located at the rear of the narrow flap, unlike the Mil-Spec flap with the catch in the center of the long side. It is there because of Adcor’s unique port dust wiper, made of engineered polymer and attached to the side of the Adcor bolt. The wiper is fitted with springs that push the wiper outwards and fill the ejection port, effectively sealing it. When the bolt moves, the wiper is slightly depressed, and during the bolt’s cycle the wiper remains in contact with the interior surface of the upper. This keeps dust and sand from infiltrating into the upper receiver around the bolt. Adcor’s wiper is intended to significantly reduce the infiltration of debris.



The weapon’s versatility is further evident in the fact that the Adcor charging handle can easily be swapped out and placed on the opposite side for ambidextrous capability.


At the rear of the upper receiver is the standard charging handle. However, Adcor’s extended bolt rod has another trick up its sleeve—another charging handle and forward assist handle. If you are familiar with the Heckler & Koch series of rifles (G-3/HK91, HK93, HK53, MP-5) then you are aware that their charging handles are located alongside the barrel forward of the receiver. As the bolt piston rod is attached to the bolt carrier, Adcor took advantage of this and attached a second charging handle to the rod.

Using the charging handle to cycle the bolt no longer requires shooters to more radically shift their shooting position in order to operate the traditionally charging handle. Since the Adcor charging handle does not reciprocate, the shooters are able to place their hand on the forend without concern of injury. The Adcor charging handle is used to charge or clear the action. It can also be used to lock the bolt open; however, that still requires manipulation of the standard bolt catch.

Adcor does not stop there, the charging handle can easily be swapped out and placed on the opposite side. Adcor leaves the traditional AR upper receiver’s charging handle so that shooters can easily operate whatever system with which they are comfortable.



While the rear of the upper receiver has a standard charging handle, Adcor’s extended bolt rod carries a non-reciprocating forward charging handle, no longer requiring the operator to radically shift shooting position in order to charge the weapon.


The BEAR upper offers everything the military could want. A simple change to existing rifles and the military would be well served with this enhanced rifle. The same upper or even complete rifle is also available to the civilian shooter, complete with the same level of features and convenience. If you as a shooter have grown beyond the standard AR, then the Adcor BEAR may be your best choice.

ETA Devastator 12 Ga


私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。

Elite Tactical Advantage’s highly capable and revolutionary tactical shotgun!



The ETA Devastator is truly revolutionary for the 11-87 design, incorporating a folding stock and radical rail system to this popular platform. Seen here equipped with a Burris FastFire II Red Dot and Insight Tech-Gear M6X Laser/Light.


Having long been a fan of the shotgun platform, I’ve taken the opportunity to test a variety of scatterguns throughout my career. Starting life as a dyed-in-the-wool pump shotgun guy, the move to semi-automatics was made in earnest about 10 years ago. As they became truly reliable, all the downsides just seemed to disappear. Clearly there are some operators out there that are as “fast as the auto” with their pump gun, but not me.



The ability to have it cycle as fast as the trigger is pressed can be advantageous on an entry or at close range. With the correct ammunition they also seem to add some credence to the pseudo-science of the “one shot stops.” All of the discussions as to the terminal ballistic performance of rifles, pistols and submachineguns just make most shotgun guys chuckle. The number of cases where the suspect was double-tapped with buckshot at close range and failed to stop are just about non-existent. With the advances in ammunition it only gets better. Buckshot patterns that are under 5 inches at 25 yards are common, so the need to change ammunition is reasonably limited. With all the rifles that go through these hands, the semi-auto 12 gauge is still my go-to-gun. A short-barreled semi-auto with a small red dot, pistol grip, and side saddle is within reach to this day.



The folding stock allows operators to bring serious firepower for covert assignments as well as fighting from a patrol vehicle.


One of the first short barreled semi-auto shotguns deployed for entry on our LE team was an 11-87 made by Scattergun Technologies. It was one of the last ones made prior to the sale of the company to Wilson Combat. Once it was tuned up to use the ammunition we used most, it ran fine, as long as we used that ammunition. Running low-brass practice ammunition could be a bit of a problem as compared to the duty ammunition. Eventually, we benched them and followed the popular move to submachineguns.
